You want the VivoKey Apex.
It will be released soon, you’ll be able to load the Not A Keycard applet for your tesla.
Unlocking your computer is also easy, you’ll find guides for fidesmo cards.
Payment is a thing… the apex could do it… but mastercard doesn’t allow that… yet.

Until that is solved (maybe in some years) you can convert payment chips that expire to an implant.
My payment implant expires in 4 years, I hope Mastercard allows payments via the apex then.
You could get a PAY and NExT to unlock computer and doors and pay. Or you wait.
